Personality disorders affect the way a person sees and interacts with the world, from attitudes to relationships to behaviors. These disorders may be caused by a genetic predisposition or environmental factors such as the influences of early childhood, or a combination of the two.
Personality disorders are organized into three clusters:
Cluster A includes disorders that are characterized by odd or eccentric behaviors.
Cluster B includes disorders that are characterized by dramatic or erratic behaviors.
Cluster C includes disorders that are characterized by anxious or fear-driven behaviors.
